Equations are:
6x+4y=24  Equation 1
2x-4y=-8  Equation 2
First find the intercepts or ordered pair for each equation.

6x+4y=24
When x=0
6(0)+4y=24
4y=24
y=6  Ordered pair is (0,6)
When y=0
6x+4(0)=24
6x=24
x=4  Ordered pair is (4,0)

Now for equation 2.
2x-4y=-8
When x=0
2(0)-4y=-8
-4y=-8
y=2 Ordered pair is (0,2)
When y=0
2x-4(0)=-8
2x=-8
x=-4  Ordered pair is (-4,0)
Now graph the points on the graph, we get the attached graph. 
Solution is (2,3)
From the graph, it is clear that the solution lies in the first quadrant.
The x-coordinate is 2 and y-coordinate is 3.

Answer: Option C, D and F are correct.

Is the given point interior, exterior, or on the circle (x + 2)2 + (y - 3)2 = 81? P(8, 4)
Elodia [21]
From the equation we see that the center of the circle is at (-2,3) and the radius is 9.

So using the distance formula we can see if the distance from the center to the point (8,4) is 9 units from the center of the circle...

d^2=(8--2)^2+(4-3)^2  and d^2=r^2=81 so

81=10^2+1^2

81=101  which is not true...

So the point (8,4) is √101≈10.05 units away from the center, which is greater than the radius of the circle.  

Thus the point lies outside or on the exterior of the circle...
